生产者:

package com.zainagou.client;

import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageProducer;
import javax.jms.Session;

import org.apache.activemq.ActiveMQConnection;
import org.apache.activemq.ActiveMQConnectionFactory;
import org.slf4j.Logger;

public class Producer {

    private static final Logger logger = org.slf4j.LoggerFactory.getLogger(Producer.class);
    private static final String brokerURL = ActiveMQConnection.DEFAULT_BROKER_URL;
    private static final String queueName = "testqueue";
    
    public static void main(String[] args) throws JMSException, InterruptedException {
        //初始化connectionFactory
        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(brokerURL);
        //创建链接
        Connection connection = connectionFactory.createConnection();
        //启动链接
        connection.start();
        //创建会话 第一个参数表示是否使用事务如果为true,只有在调用session.commit()时才能提交消息到队列,消费者才能接受
        Session session = connection.createSession(true, Session.AUTO_ACKNOWLEDGE);
        //创建队列
        Destination destination = session.createQueue(queueName);
        //创建生产者
        MessageProducer producer = session.createProducer(destination);
        //创建消息
        StringBuffer buffer = null;
        for(int i = 0; i<=15; i++){
            Thread.sleep(3000);
            buffer = new StringBuffer();
            buffer.append("欢迎使用ActiveMQ");
            buffer.append(i);
            logger.info(buffer.toString());
            Message message = session.createTextMessage(buffer.toString());
            producer.send(message);
        }
        //使用事务是提交事务或回滚事务
        session.commit();
        //session.rollback();
        connection.close();
    }
}

消费者:

package com.zainagou.client;

import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageConsumer;
import javax.jms.MessageListener;
import javax.jms.Session;
import javax.jms.TextMessage;

import org.apache.activemq.ActiveMQConnection;
import org.apache.activemq.ActiveMQConnectionFactory;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class Consumer implements MessageListener {

    private static final Logger logger = LoggerFactory.getLogger(Consumer.class);
    private static final String brokerURL = ActiveMQConnection.DEFAULT_BROKER_URL;
    private static final String queueName = "testqueue";
    
    public static void main(String[] args) throws JMSException {
        //创建ConnectionFactory
        ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(brokerURL);
        //创建connection
        Connection connection = connectionFactory.createConnection();
        //打开connection
        connection.start();
        //创建会话
        Session session = connection.createSession(true, Session.AUTO_ACKNOWLEDGE);
        //创建会话目标
        Destination  dest = session.createQueue(queueName);
        //根据会话目标创建消费者
        MessageConsumer consumer = session.createConsumer(dest);
        //初始化MessageListener
        Consumer sumer = new Consumer();
        //给消费者设置监听对象
        consumer.setMessageListener(sumer);
    }

    @Override
    public void onMessage(Message message) {
        try {
            logger.info("接受消息:"+((TextMessage)message).getText());
        } catch (JMSException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        
    }
}
